You've guessed it. Its out-of-the-box sendmail.

If I run the script (or just send a mail) on the command line using 
sudo, then it's sent as me and not root. Same happens if I su to root first.

The only way I can get it to be sent from root is if I explicitly login 
as root.

So it looks like it isn't. What can be the cause of this then?


Thanks for your help.
